摘要: A method of determining the actual position of a control surface (27). The method comprises receiving a signal (34) representative of a required position of the control surface (27), repositioning the control surface (27) in response to the signal (34) by moving an actuator (26), measuring a secondary position indicator, calculating the actual position of the control surface (27) on the basis of the secondary position indicator and, comparing the actual position with the required position.

摘要: A motor control apparatus includes an error calculation unit which calculates an error between a position of a movable unit and a position of a driven unit, a memory unit which memorizes the error in association with a torque command value as an initial error, and a compensation amountcompensation amount calculation unit which calculates a compensation amountcompensation amount for compensating an elastic deformation amount of an elastic factor between the movable unit and the driven unit. The compensation amountcompensation amount calculation unit calculates the compensation amountcompensation amount based on the initial error held by the memory unit, the torque command value held in association with the initial error, and a torque command value calculated by a torque command calculation unit when a motor rotates reversely.

摘要: A method and apparatus for controlling a stepper motor and for force sensing and force control. Stepper motor drive waveforms are provided which are constructed of a sequence of stairsteps, the size and duration thereof being determined as a function of the desired rotational velocity of the stepper motor. Means and a method for accelerating the stepper motor by varying the step size and step duration of the stairsteps in the drive waveform are discussed. Additionally, means and a method are discussed for sensing and controlling the force applied by the stepper motor to a load by way of evaluating the displacement of the actual position of the stepper motor shaft from the commanded or desired position of the shaft. Means and a method for implementing a compliant function in a similar manner are described.
